Official description

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated users to inject malicious script by uploading a file with HTML/script markup embedded in its filename, which bypasses the paramFilter since uploaded-file names arrive through $_FILES rather than $_GET/$_POST. Attackers can upload a file with a crafted name such as an SVG onload payload to have the unsanitized filename stored and later rendered to other users, resulting in script execution in their browsers.
